I have been reading search results for a week. I have gotten some good stuff but I haven't found what I am looking for.

What are the common trouble spots of a 300 (I haven't found any yet)?
Is there over-heating problems on slow technical trails?
What vendor has the most spare parts?
How lean is the stock jetting?
I am going to be racing this quad in XC series in VA (read that as no jumps, low speed), any suggestions for getting it ready to race? I am going to do the normal stuff: air filter, oil/ filter and plug.

 

Get a shock relocating bracket on ebay and put trx450r front shocks on it with 400ex a-arms. This is what im doing to mine. With gas shocks you will have a much smoother ride and a wider one with the a-arms. all this stuff matches up too so no grinding or cuting.

 

Anyone else with suggestions???
